Blair surname meaning
From a Scottish place or landscape described by Gaelic blàr, an open plain or field.
Confidence: Likely. The main story is well supported; some details of the deeper root are less certain.
The short story
Blair is chiefly a Scottish place surname, associated with localities and landscapes named from Gaelic blàr. The word is commonly explained as an open plain or field, and in some contexts as a battlefield; those glosses describe related landscape vocabulary rather than one guaranteed village. Blair could therefore identify someone from a particular Blair place or from a district marked by open ground. Blar and older spellings appear in related records, while the modern form became widespread in English-speaking countries. The habitational classification is well supported, but the precise landscape translation remains likely rather than certain.
